When running offline, snapshot artifcats cannot be resolved even if they have previously be dowloaded from a repository. This happens when attempting to depend on a snapshot version of a module downloaded from a repository. If the snapshot version of the module is built and installed locally, the problem goes away.

I will attach two projects (in a tar file) that have minimal external dependencies, and the debug output of trying to build. Here are the steps to reproduce:

Environment:
Maven 2.0.8
Linux 2.6.18
Artifactory 1.2.5 (rev. 1154)
(this has also been reproduced by a colleague on a Windows machine).

Preliminary steps:
1) Modify the pom files to refer to your actual repository instead of http://localhost:8081/artifactory/jumptap-snapshots
2) Build maven-test-project1
3) Upload the pom and jar for maven-test-project1 to your repository.

Steps that cause the error to happen:
1) Delete maven-test-project1 from the local repository.
2) Build maven-test-project2 without the offline flag (mvn install). This build is successful (and downloads maven-test-project1 to the local repository).
3) Build maven-test-project2 with the offline flag (mvn -o install). This build fails, unable to resolve the maven-test-project1 artifact.

Steps that cause the error not to happen
1) Build maven-test-project1 locally. This build is successful.
2) Build maven-test-project2 without the offline flag (mvn install). This build is successful.
3) Build maven-test-project2 with the offline flag (mvn -o install). This build is successful.
